Brief Summary: Study RIN-PF-305 is designed to evaluate the safety and efficacy of inhaled treprostinil in subjects with progressive pulmonary fibrosis (PPF) over a 52-week period.
Detailed Description: Study RIN-PF-305 is a Phase 3, multinational, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of inhaled treprostinil in subjects with PPF over a 52-week period. Subjects will be randomly allocated 1:1 to receive inhaled treprostinil or placebo. All subjects will initiate inhaled treprostinil or placebo at a dose of 3 breaths administered 4 times daily (QID) and will titrate to a target dosing regimen of 12 breaths QID. Study drug doses may be titrated up as tolerated, until the target dose or maximum clinically tolerated dose is achieved. Once eligible, 6 Treatment Period visits to the clinic will be required at Weeks 4, 8, 16, 28, 40, and 52.

Efficacy assessments include spirometry (forced vital capacity \[FVC\]), time to clinical worsening, time to first acute exacerbation of interstitial lung disease (ILD), overall survival, King's Brief Interstitial Lung Disease (K-BILD) questionnaire, plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration, supplemental oxygen use, and lung diffusion capacity (DLCO). Safety assessments include the development of adverse events (AEs)/serious adverse events (SAEs), vital signs, clinical laboratory parameters, and electrocardiogram (ECG) parameters.

Subjects who complete the Week 52 Visit may be offered the opportunity to enter an open-label extension (OLE) study after completing the final study visit.
